Question

我编写了以下代码来了解fql multiquery的工作原理：

include_once "fbmain.php";
try{     
$your_id=xxxxxxxx;
     $fql= '{
     "friends":"SELECT uid2 FROM friend WHERE uid1='.$your_uid.',"
     "friendinfo":"SELECT * FROM standard_user_info WHERE uid IN (SELECT uid2
                  FROM #friends)"
             }';
$res = $facebook->api_client->fql_multiquery($fql);   
   }
catch(Exception $o){
        d($o); // d() is function to print
    }

但输出显示错误

在第9行的非对象上调用成员函数fql_multiquery（）

我也尝试过其他查询而不是这两个，但问题仍然存在。我正在使用php sdk 3.0。

帮忙。

Answer 1

我不使用Multi Query，因为fql已经移动到图形api。相反，我使用批量请求。这是一个/ feed请求的示例，前10个结果的注释和来自前10个帖子的固定链接的fql multi。我确信这对你所需要的东西来说有点过分了，但这是我用混合图形和fql以及使用名称功能的最好例子，这似乎是你需要携带的朋友。

Answer 2

看起来很像

的实例化问题

$facebook->api_client

值得注意的是，在[standard_user_info]中，[uid]列的类型为 string ，因此您可能还需要添加引号。

根据FB文档，FQL多查询应该比后续批处理调用更快。 https://developers.facebook.com/docs/reference/fql/
